If you get a free N hours, you should try moving a pcode module from
OS-9 to one of those, or vice-versa, and let us know what happens. 

I do know that the OS-9 Pascal compiler sticks an empty OS-9 module on
the begining of the pcode file as a header.  You'll have to split that
off/add it on.

My housemate has a TI-99.  Interesting but unfortunately crippled
machine.  I'd heard that it had a P-system.  Does the Pcode engine run
directly on the CPU or is it a GROM?

You have a running Apple 3?  Wow, I'd be jealous, but then you might
give it to me or something. ;-)

Does the P-System define a terminal type or is it just a dumb

Yeah, GUIs and their "we must have the same look-and-feel" fanatics
are one of the strong forces that pull apart JVM compatibility.
